` TO ALL WHOM IT MAY CONCERN: y Be it known that I, JOHN B. Douennnrr,ot Rochester, in the county of Monroe, and Stute-,of New York, have-invented certain new and useful Improvements in Machines for TurningBarrel-Held end I do-he'reby declare that the following is a full,clear, and e'xact description thereof. reference beinghnd tothspccompanying drawings, ranking part of this specification, in whichll Figure 1, `'Sheet A, is a side elevation of my invention, the shafts Qand R'bing shown 1n section, indicated by the red 'line o in iig. 4,Sheet B. 4

F igure is a detached elevation of the reversesidc of theclamping-pleite M and the topof"the,lupporting column A, and showing thepawlp. l i

Figure 3 is a detached view of thc reverse side of' the double orcompound 'cam C', which work! the lever t X and the clamping-lever L'. vi Figure 4, Sheet B, is a toptview of the parts below the planeindicated by the 'red line o ih iig. 1. Similar letters indicatecorresponding parts in all the figures. 4 This invention consists inproviding an automatic barrel-head turning machine, and its nature'willbe better t understood by reference to the drawings and specification. vl To enable others to make and use my invention, I will describe itsconstruction and operation. i, The supporting columns A and B are castupon the base or bed-plate C. There is a journahboxpor hanger,

, l), cast upon theside of A. The saw-frame F is attached byscrew-bolts@ to th'ecross-bar E, castV upon or otherrsise attached tothe top of the vertical shaft G. This shaft is rnade with a largeopening transversely through the lower end for the shaft I lto pasethrough loosely. The foot of the shaft is sustained by an adjustable orscrew centre, a, by means of` which it is kept with thc collar 'I1snugly against hanger D, The cro`ssbar E is provided at one end withVnylug, d, through which the set-screw c is tapped. This screw has agrooveturned in the head to receive the foi-kf, which is fixed to theend of the saw-frame. By turning the screw one wayor the other whenthebolts s are loosened the saw-frame may be set so as toV throw the sawfurther from or nearer to hhe centre of the 4clamping-disks, so as tocnt larger or smaller heads, as may be desired, with the same 1 machine,and after the adjustment is effected the bolts a should be tightened,The set-screwgie tapped through the lug l, and the end strikes againstthestop e, cast upon the column A, and limits the throw of the` saw Sinv that direction. There is a heavy strap-spring, IL, bolted to thcbase-plate C, so as to press against the arm J of the shaft AG and forcelthe saw back from the working position as soon as the head is properlyturned. There is an arm, K, fig. 4, Sheet B, on the reverse side ofshaft Gr,'to which is hinged the lrodL. This rod is made in two vparts`and connected together by a malo and female screw, and ajuin-nut, u,-whereby the rod may be lengthencd or shortened to compensate for anyvwenr,or to change the throw of thc saw totturn thick or4 thin lnsading.`rThe opposite end of the rod is supported in a hanger, 0, and itispressed forward and held by `the cam-plate P long enough tokcep thesaw in its worhingposition, while the clamp-disks M' and N shall makeabout two or thre inches (more or less) more than a full revolution,when it is released by the cam, and is forced back by the spring H. Theshafts I, (2,: and R are Veach, hung in suitable pillan-blocks T. Theblock T" answers also for the step in whichthe lower end of the verticalshaft U runs. This shaft is supported above byu bearing through the-armor hanger V- of the column B. This shaft I is driven by the screw orworm-gear and thc band B from the saw-'mandrehihndit-has a constantmotion, as has also thc cam-shaft R, but the vshafts and Y have nnintermittent motion produced by the mitre pinion F being feathered tothe shaft U and madoto slide upon it verticallyat proper intervals by'tho forked lever X, which is hinged to the 'column B, as seen in figs.1 and 4, and is coupled to the pinion F by lugs c', iig. 4, which takein a groove, turned in the hub, and the outer end of i the lever being,operated by the. double or compound cam Chgs. 3 ,and 4. The topgof thespiral spring D u rests'against the collar E', which is ixed to theshaft'U, and the other end forces the pinion into gear with its fellowGf whenever the said cam is in a position to relieve the end 'ofthetlever.. The pinion P is feathered to thehai't Y, which is madetoslide longitudinally. This shaft is provided `with a xedcollar, C, andthe spiral sprigj d rives the shaft to the right when permitted by therecess r in the cam C', relieving the end of the leverlL, which is hungto u. projecting hanger, H, cast on them-m V. vThe upper end ofthislever is i forked, and' is provided with s pivoted nut, n', throughwhich the set-screw c passen..4 The end of the screw.

sus@ 2 maybe pointed and made to .enter or restin the centre in the endof the shaft Y. l The space between the clamping-'collars M and N, when'closed together, isregulated byths set-screw, and the machine is therebyadjusted to any desired thickness of heading. The clamping-disk M, orcircle, (for it may be made in skeleton form,) is hung to this shaft andmoves with it. The other clainp-plateor collar N is hung or has'its axisin the top of column A', asseen in fig. 2, and is provided with aratchet, 7', and pawl, p', to prevent itfrom turning .backward at anytime. There isa vertical rod, m, 'attached 't'o each side. of the columnB. To each of these is' fixed, 'by a setscrew', u, `an arm', v.' vIlnthc 'end of-tliesc arn'is is hung a roel-shaft having two or. morearms orrests t. The crank-armi@ of' this shaft is connected to 'thecounterbalanced lever y bythe rod x. By means of'the sobscrewslt andtheholes e inthe rcdthe rock-shaft maybe raisefl'or lowered to adaptthe-machine to larger or smaller heading. 'The lever y is operated bythe earn C". The shaft I passes `loosely through the colf .umns andthrough the web W which .connects them together, as shown.

.When the parts .are all /properly adjusted relatively the heading t'obeturned is placed bythe attendant Vuponthe,rests t of the vrock-shaft,they being in the position'o'f the dotted lines t. The clamps are thenclosed .bythe cam C', forcing the end of'the lever L to the outercircle. The rests then drop to their present position. The-saw sthenswung into its working position.- The end of-thc lever X drops frein theposition shown in iig.' 3, having passed thciraised port-in of' the sidecams or bearings of thecain to the position shown in fig. l. The ,pinionFis thereby thrown in gear, and when the clamps arc turned once around,and two inches, more or less', beyond the cam P, relieves the end of therod L, andi-the springl Hthrows the saw back, immediatciy after which`the feedpeasesiby the-pinion being throwuont of gear, and the clamp' Nis released by the end of the.

lever L dropping into the notch r', as before described and shown infig. 3, and et the saine inst-ant or a little l previous the rests t arereadjusted.` s soon as the clampspa-rt the finished head drops outandthe attendant supplies the material for another, and so on.

' I propose to use' a more dis'hing saw for turning half-barrel headsthan for those for whole'barrels. The

machine is driven by the hand. B from the saw-mandrel, that` beingdriven by an ordinary fiat band on the pulley: A.y

What I claim as my invention,'and desire to secure by Letters Patent,isl. An' automatic barrel-head turning machine, .when the automatic'movements or adjustments are produced `by suitable cams, P,`C andC,and'tl1eir necessary connecting-rods, substantially as herein shownand described. 2. In combination with .the slidingorelaniping-shaft Y,the feathered pinion P, spiral spring J, coiiar C",

lever L', and cani C', they being` arranged and operating conjointly inthe manner and forl thc purposes shown and described. V

` 3. Thearrangement of the set-screw k, pivoted nuti, and thev leverL,in connection with thc clampingheadsh-Iand N, substantially as shown anddescribed end for'the purposesk set forth.
